DEMOUNTABLE METAL PARTITION Filed May 24. 1951 1a Sheets-Sheet 1e UnitedStates Patent DEMOUNTABLE METAL PARTITION Robert C. Johnson and Ralph S.Millard, Jamestown, and Reuben T. Carlson, Scarsdale, N. Y., assignorsto Steel Partitions, Inc., Jamestown, N. Y., a corporation of New YorkApplication May 24, 1951, Serial No. 228,025! Claims. (Cl. 18934)' Thisinvention relates to a demountable metal partition presenting improvedstructural features over the metal partition shown in iohnson Patent No.2,360,500.

This improved demountable metal partition comprises flush panel units,glazed panel units, and door frame units having similar shaped framinguprights which greatly simplifies fabrication and interchangeableerection of the separate sections. The flush panel units are eachassembled from a pair of wall facing sheets interiorly faced with asound deadening layer, and are provided with rebent edge portionsdesigned to engage the outturned flanges forming a part of the framinguprights. Spaced horizontally extending spacing channels present theside flanges thereof in abutting contact against the sound deadeninglayer of the panel facing sheets, the space between the spacing channelsbeing filled with sound deadening packing. The spacing channels withinthe panel unit are provided with spaced tongues extending from each endthereof inserted into conformed slits cut in the framing uprights. Astretcher stud is threaded into one end of each spacing channel with thehead portion thereof extending through the adjacent framing uprightpermitting the studs to be conveniently manipulated to tension thefacing sheets and remove waves and irregularities from the surfacesthereof.

The glazed panel units are also constructed from identical framinguprights having sound insulated metal facing sheets extending to anyconvenient height desired. A sash frame is separately fabricated toreceive either one or two panes of glass and then telescoped between theupper portions of the framing uprights to snugly seat against the upperedges of the applied facing sheets to form a smooth and flush jointtherewith. The glass retaining molding comprises a fixed molding stripsecured to and forming a part of the sash frame, the glass beingretained in position by removable molding strips.

Supporting and levelling devices are provided which are secured to thebuilding floor along the partition run to insure accurate alignment andlevelling of the partition sections as erected thereon. Only three typesof connecting clips are required to rigidly connect the panel and doorframe units together under substantially all partition run conditions.The straight run connecting clips have hook portions removablyinsertable into the slots formed in the framing uprights to connect theadjacent panel and door frame units in straight run alignment. The innercorner connecting clips have hook portions insertable into the adjacentclip receiving slots when adjacent units are arranged in angularrelationship. The outer corner connecting clips also have hook portionsfor insertion into the adjacent paired clip receiving slots at the outercorner of the angularly arranged panel units. Removable post caps spanthe space between adjacent uprights and are designed to resilientlyengage rolled edge portions formed on the connecting clips.

The cornice assembly comprises a cornice frame which extendscontinuously over the erected panel sections, formed from paired channelshaped members arranged 2,766,855 Patented Oct. 16, 1956 back to backproviding a rigid I-beam construction presenti'ng two-compartment Wiringraceways. The wiring raceways are enclosed on each side of the partitionby continuous cornice covers which snap into removable engagement withthe outwardly extending flanges of the cornice frame permittingconvenient access at all times to the wiring and conduits containedtherein; The cornice frame is detachably secured to the unit uprights byfixed lugs and removable keys.

As a further feature, this improved partition incorpo rates a floatingbase assembly comprising a floating base frame positioned between thelower projecting ends of the framing uprights of each panel unit. Eachfloating base frame may be economically constructed from a pair ofgenerally channel shaped sheet metal members arranged back to back toprovide a two compartment raceway there in which align with cablewayholes cut in the lower end extensions of the framing uprights, therebypermitting wires and cables to be strung the full length of thepartition run. The outwardly extending flanges of each base frameterminate in upwardly extending legs to which baseboard members may beremovably secured. The baseboard members may be economically fabricatedfrom sheet metal strip cut in any desired length and are installed oneach side of the partition to extend the full length of the partitionrun, the terminal ends of the baseboards adjacent the door frame beingcovered by removable plinth blocks. The baseboard members may be removed and replaced after installation, providing convenient access tothe wiring and conduits contained in the base frame sections. Thisimproved base assembly conceals floor irregularities, provides anattractive trim for the lower ends of the partition sections, andpermits insertion of floor carpeting under the lower edge thereof.

The Wall filler assembly comprises a framing upright secured to theadjacent framing upright of the adjacent panel or door frame unit bystraight run connecting clips, and a wall trim channel removably securedto the adjacent Wall of the building, the space therebetween beingcovered by separate facing sheets having insulating felt secured to theinside surfaces thereof. The ceiling filler assembly comprises partswhich are fabricated in the shop for field erection to extend from thecornice assembly to the ceiling. The cornice filler framing comprisespaired channel shaped verticals extending through preformed holes in thetop and bottom flanges of the cornice frame and into the space betweenthe adjacent framing uprights of adjacent pat-ti tion sections. Aceiling trim channel containing a spacing channel is removably securedto the ceiling, and a corresponding spacing channel is secured to theupper flanges of the cornice frame. Metal facing sheets are applied tothe thus erected framing and the space between the ceiling filler facingsheets may be filled with sound deadening packing as the facing sheetsare erected in the field. i

This improved demountable partition may be economically manufacturedfrom a minimum number of parts and erected with minimum fitting in thefield to accommodate substantially all field conditions.

Fig. 1 is intended to illustrate a typical installation of thisdemountable metal partition wherein the partition is shown erected onthe building floor W over which a ceiling Z extends, the partition runsbeing joined to a vertical building wall Y. The installation shown inFig. 1 illustrates the manner in which this partition may be erected tosatisfy straight run, angular run, and T-run conditions as normallyencountered in the field.

The partition as illustrated comprises a series of erected partitionunits including flush panel units A, glazed panel units A, and doorframe units I which may be interchangeably arranged as desired. Thepartition units are shown capped by a cornice assembly E with a ceilingfiller assembly H mounted on the cornice assembly and extending to theceiling Z. A wall filter assembly G is shown in abutment against thepermanent wall Y of the building, filling the space between the wall Yand adjacent glazed panel section A.

Partition unit supporting and leveling devices B, each comprising afloor block having flat leveling shims 65 capped by an aligning shim65', are secured to the floor along the partition run and positionedbetween the adjacent vertical edges of adjacent partition sections tolevel the partition sections and maintain them in accurate alignment.

The adjacent vertical edges of the partition units arranged in straightrun alignment are detachably connected by normally concealed straightrun connecting clips C normally covered by removable pilaster caps D-resiliently secured to the connecting clips. The inner corners ofadjacent angularly extending partition units are detachably securedtogether by inner corner connecting clips C, and the outer cornersthereof are detachably secured together in rigid assembly by outercorner connecting clips C normally concealed from view by a cornerpilaster cap F which is resiliently but removably secured to theattached outer corner connecting clips C".

The floating base assembly F extends along the build ing floor with itsbase frames 110 contained between the framing uprights of the panelunits, the base frames 119 being normally concealed by removablebaseboards 124 extending along each side of the partition runs,providing an attractive finishing trim which conceals floorirregularities. A door 171 is shown mounted within the door frameassembly I. The lower ends of the door frame uprights are covered byplinth blocks 255 against which the adjacent ends of the baseboards 124abut.

The cornice assembly E comprises a continuous cor-- nice frame 94 ofI-beam formation which caps the erected. partition sections and greatlystrengthens the erected partition. The cornice frame 94, providing a twocompart-- ment wiring raceway, is capped on each side thereof byremovable cornice covers 106.

By removing the cornice covers from the cornice frame: 94, thebaseboards 124 from the floating base frames 11%, and the pilaster capsD and D' from the partition section connecting clips C and C", completeaccess may be had for the installation or repair of conduits and ca blesleading to outlets installed at any desired location on the erectedpartition.

Panel units The interchangeable flush panel units A, presenting 6substantially flush facing surfaces throughout their height andconstructed more particularly as illustrated in Figs. 2 to 12 inclusiveand Figs. 22, 23 and 24, comprise ver tical and horizontal framingmembers constructed and assembled to provide a strong framework whichsupport the panel facing sheets. The panel framework comprises a pair offraming uprights 1 each formed from a single strip of relatively heavysheet metal rolled into double 8 formation as illustrated in Figs. 2, 3and 4 to provide a main web 2, a pair of parallel extending inner legs3, and a pair of intermediate webs 4 flaring outwardly from the innerlegs 3 and extending substantially parallel to the main web 2, theintermediate webs 4 each terminating in an outturned outer leg 5 spacedfrom and extending substantially parallel to the inner legs 3.

The framing uprights I extend the full height of the panel unit and areconnected together by a series of horizontal extending spacing channels16 which are spaced a distance of one to two feet apart. Each spacingchannel 16 comprises a web portion 17 and side flange portions 18 asshown more particularly in Figs. 2, 5 and 8 to 11 inclusive. A pair ofstruck out tongue elements 19 extend from each end of the spacingchannel and are designed to be inserted into corresponding tonguereceiving slits 7 cut through the intermediate webs 4 of the framinguprights 1 to be thereby supported. After assembly of the panel unit hasbeen completed, the inserted tongue elements 19 may be bent or twistedto secure the spacing channel 16 to the framing uprights 1.

Each spacing channel 16 may be reinforced by forming a longitudinalextending reinforcing rib 20 in the web portion 17 thereof. One end ofeach spacing channel is formed to present a pair of alternate spanners21 which are bent downwardly into arcuate shape and a pair ofintermediate spanners 21' which are bent upwardly into arcuate shape.The companion spanners 21 and 21' are internally threaded and are shapedto provide a threaded hole of uniform diameter designed to receive thethreaded shank portion 24 of a stretcher stud 23 as shown in Fig. 12. Aclearance slot 22 separates the adjacent end of the reinforcing rib 2!from the threaded spanners to provide room for the inserted end of thethreaded shank portion 24 of the stretcher stud 23.

The stretcher stud 23 presents a flared base portion 25 of substantialarea designed to snugly seat against the inside face of the main web 2of the adjacent framing upright 1 as shown in Fig. 2, with the roundneck portion 26 thereof extending through a corresponding hole 6 in theadjacent framing upright 1 so that the hole 6 provides a bearingtherefor. The rounded neck portion 26 terminates in a rectangular headportion 26' to which a wrench may be applied to manipulate the spreaderstud 23.

A wall forming panel sheet 10 is mounted on each side of the framingformed by are vertical uprights 1 and the horizontal spacing channels16. As shown in Fig. 6, the facing sheet 10 presents a squared edgeportion 11 along each vertical edge thereof which terminates in a rebentlip portion 12. The upper horizontal edge of the facing sheet 10 is alsoprovided with a squared edge portion 13 which terminates in a downturnedlip portion 14. The inside face of each panel sheet 10 has a fibrousbacking sheet 15 cemented thereto and covering substantially the entireinner surface area thereof as shown in Fig. 6. The fibrous backing sheet15 is preferably made of a fibrous felt which has sound-deadeningqualities.

In assembling the flush panel unit A in the form shown in Fig. 2, theuprights 1 are applied to one of the panel sheets, and the spacingchannels 16 placed therebetween. Insulating filler 29 isthen placed inposition between the framing uprights 1 and the spacing channels 16. Thesecond facing sheet 10 may then be telescoped endwise over the outerlegs 5 of the framing in the manner of a sliding cover, with the squarededge portions 13 of the panel sheets hooked over the outturned flangeportions 18 of the uppermost spacing channel 16 in the manner shown inFig.2. By means of a suitable wrench, the headportions 26' of thespreader studs 23. projecting through the holes din the adjacent framingupright are manipulated to spread or separate the framing uprights 1until the facing areas of the facing sheets are stretched or drawn tautto place the desired drum head tension on the facing sheets 10, therebyremoving all waves or irregularities, providing a wall surface ofprecise smoothness. This stretching action also serves to press theinsulating sheets attached to the interior of the facing sheets 10against the flange portions 18 of the spacing channels 16, therebypreventing subsequent buckling of the facing surfaces or the productionof metallic ring when the facing sheets are drummed upon. As shown inFig. 2, the lower end portion of each framing .uprightl extends somewhatbelow the lower edges of the facing sheets 10 to provide room for wiringand conduits therebelow which may be strung through aligned openings 9provided in the main web 2 of the framing uprights. Lug plates 27 arealso secured as by welding to the upper ends of the intermediate webs 4of each framing upright as shown in Figs. 2 and 7. Each lug plate 27presents a pair of upwardly projecting spaced lug portions 27' eachprovided with a hole 28 therein for receiving a cornice securing key 28'to thereby detachably secure the cornice assembly to the partitionunits.

Each glazed panel unit A as illustrated in Figs. 13 to 21 inclusive, isconstructed from a pair of framing uprights 1 upon which panel formingsheets ltl'are mounted to extend to the desired height. The lower halfsection of g each glazed panel unit A is constructed similar to theflush panel units A illustrated in Figs. 2 to 12 inclusive andheretofore described, and wherein spacing channels 16 areemployed asshown in Fig. 10 having tongue elements 19 inserted into correspondingslits 7 formed in the framing uprights'l, spreader'studs 23 beingassoci-' ated with eac h spacing channel 16 whereby the desiredtensionmay be applied to the panel facing sheets 10'.

The upper horizontal edge of each panel facing sheet 10' is providedwith a squared edge portion 13 designed to seat over the free edge ofthe adjacent flange portion 18 of the uppermost spacing channel 16 asshown in Figs. 13, 14 and 15 and terminates in an upturned lip portion14' to fit the superimposed sash frame 30.

The space between upper sections of the framing uprights 1 is designedto receive the glazed sash frame 39 which comprises a pair of verticalframing members 31 and a pair of horizontal framing members 36. Eachvertical framing member 31 as shown in Figs. 14, 16, 17 and 19 comprisesa web portion 32 terminating in outturned flange portions 33. Eachoutturned flange portion 33 presents an outwardly offset facing portion33' and has a squared vertical edge portion 34 terminating in rebent lipportion 35 to thereby provide guideways for the sash frame whentelescoped between the framing of the sash fuame.

tion until the squared edge portions 39 thereof are brought into seatingengagement with the squared edge portions.

Mouldings are provided to removably retain a glass pane 41 within thesash frame, 30 as shown in Figs. 16,

17 and 19. The glass moulding may comprise fixed moulding strips 42assembled to provide a fixed moulding frame. Each fixed moulding strip42 presents a base portion 43 which may be secured as by welding 43 tothe adjacent base portion 32 or 37 of the respective vertical orhorizontal framing members 31 and 36. Each fixed moulding strip 42presents a groove forming wall portion 44 rising from the base portion43 thereof which merges into the attractively contoured moulding portion45 which terminates in an inturned foot portion 46 seating against thebase portion of the adjacent framing memher. An offset flange portion 47terminating in a flared lip 48 extends from the base portion 43, theoffset flange portion 47 being formed to resiliently retain a removablemoulding strip -51} associated therewith. The adjacent ends of the fixedmoulding strips 42 are beveled and interfitted to provide a finishedmoulding frame.

Each removable moulding strip is constructed to be applied to theopposite face of the installed window pane 41 and to 'removab'lyinterlock with the offset flange 1 portion 47 of the fixed mouldingstrip 42. Each removfixed moulding strip 42, with the foot portion 52 ofthe removable moulding strip seating against the base portion 43 of thefixed moul-ding strip 42. The adjacent ends of the removable mouldingstrip 50' are beveled so as to interfit together to provide asubstantially continuous removable moulding frame.
